Management of testicular rupture with a large tunical defect may not be feasible without excision of viable tissue. This study describes the use of a vascularized tunica vaginalis flap, without debridement of viable tissue, in four adolescents. Postoperative ultrasound showed good blood flow and 80% volume of the contralateral testis in two cases. Postoperative exam revealed normal exam and ultrasonographic appearance in three patients, the fourth was demonstrated to be small and undescended during evaluation of contralateral testicular torsion...

Acute scrotal abscess is an extremely rare condition in neonates and may mimic testicular torsion. Most of these abscesses have reportedly been due to Staphylococcus and Salmonella spp. infections. We herein report a unilateral acute scrotal abscess in a preterm infant born at 26 weeks in whom Propionibacterium acnes was isolated from the collected scrotal fluid culture. To our knowledge, this is the first case report implicating P. acnes as a causative agent of neonatal scrotal abscess. Based on such findings, P...

BACKGROUND: Testicular damage due to spermatic cord torsion may lead to infertility. It is probably because of changes in oxidative stress factors such as malondialdehyde. OBJECTIVE: To investigate the protective effect of melatonin (MLT), as an antioxidant, on testicular damage induced by acute unilateral spermatic cord torsion and detorsion (T/D) in rats. MATERIALS AND METHODS: In this experimental study, 48 adult male Wistar rats were randomly divided into three groups (8 rats/group): sham group underwent right scrotal surgery only...

Testicular torsion or torsion of the spermatic cord is one of the most serious urological conditions. It causes testicular injury, which potentially leads to male subfertility. The turning of the spermatic cord and spermatic structures around themselves results in biochemical and histological changes; however, following testicular detorsion, tissues undergo reperfusion that causes more severe damage than that induced by ischemia. Since the primary causes of testicular damage are reactive oxygen species production, an increase in intra-mitochondrial calcium concentration and an increased rate of cellular apoptosis, different medications may potentially be effective...

INTRODUCTION: Testicular torsion threatens testicular viability with increased risk of loss with delayed management. Still, healthy adolescents continue to be transferred from community hospitals to tertiary hospitals for surgical management for torsion even though adult urologists may be available. We sought to determine reasons behind patient transfer and to evaluate whether transfer to tertiary centers for testicular torsion leads to increased rates of testicular loss. MATERIALS AND METHODS: A retrospective chart review was performed for patients presenting to our free-standing pediatric tertiary care facility with surgically confirmed testicular torsion during the 5-year period between January 2011 and January 2016...

BACKGROUND: Segmental testicular infarction is a very rare condition, which can mimic a testicular torsion or testicular cancer. Correct diagnosis is difficult but it is important to avoid unnecessary radical treatment. CASE PRESENTATION: We report a clinical case of a 36-year-old white man who presented at our emergency department with subacute testicular pain. A urine analysis, Doppler ultrasound, surgical exploration, blood analysis, and magnetic resonance imaging were performed to diagnose his condition, to exclude a testicular torsion, and to raise confidence in its non-malignancy...

Acute scrotum is one of the most common urologic emergencies in children and adolescents. This condition involves acute testicular pain, which is often accompanied by scrotal swelling and erythema. It is most important to distinguish between cases that require immediate surgery and those that can be treated conservatively. As patient history and physical findings may not always be unequivocal, ultrasound with Colour-Coded Doppler Sonography is the imaging modality of choice for further evaluation. Testicular torsion and other differential diagnoses such as epididymitis, appendiceal torsion, intratesticular haematoma after trauma, or complicated inguinal hernia have to be considered...

A differential diagnosis of testicular torsion and epididymitis has serious importance for testicular health. In emergency conditions, if testicular torsion goes unnoticed and epididymo-orchitis is diagnosed, organ loss may occur. This study aimed to evaluate the usefulness of haematologic parameters for the diagnosis of both testicular torsion and epididymo-orchitis and for differential diagnosis of these two diseases. Patients were divided into three groups as those undergoing surgery for testicular torsion, those receiving medical treatment for epididymitis and a healthy control group...

OBJECTIVES: To assess the long-term evolution of the testicles preserved after testicular torsion (TT). MATERIAL AND METHODS: We realized a prospective study by ultrasound of patients diagnosed TT that underwent orchidopexy. We reviewed 85 patients treated for acute scrotum (2004-2014), finding 49TT. We excluded from the study 15 perinatal torsions, 14 orchiectomies and 5 patients who refused to participate. We analyzed 15 patients, comparing testicular volumes between affected and contralateral testes, and the difference in volume between the two testes of the 15 cases with 14 control patients (Mann-Whitney U test)...

INTRODUCTION: Testicular torsion (TT), a common surgical emergency worldwide, is typically treated with orchiectomy or orchiopexy. It is widely accepted that the chance of salvaging the testicle declines with time and degree of torsion. The impact of ethnicity on outcome is less well understood, and the association between weather and onset of TT remains a controversy. OBJECTIVES: It is important to know the signs of TT so that appropriate treatment can be given quickly...

Oxidative stress plays a critical role in the process of testicular torsion and detorsion (T/D). The purpose of the present study was to investigate the protective effect of polydatin (PD) on testicular T/D injury. Rats were randomly divided into three groups, a sham group, a group subjected to 2h torsion followed by 24h detorsion and a group subjected to T/D and injected i.p. with 20mgkg-1 PD 30min before detorsion. Unilateral orchiectomy was performed after 24h of reperfusion. Half the testes were prepared for histological examination by haematoxylin-eosin staining and the terminal deoxyribonucleotidyl transferase-mediated dUTP-digoxigenin nick end-labelling (TUNEL) technique...

We identified factors associated with delay in presentation and misdiagnosis of testicular torsion. Compared with acute cases, delayed presentations were more likely to report isolated abdominal pain, developmental disorders, and history of recent genital trauma. Failure to perform a genitourinary examination or scrotal imaging was associated with misdiagnosis.

Acute idiopathic scrotal edema (AISE) is regarded as a rare cause of scrotal pain, swelling and erythema. Testicular torsion, torsion of the appendage, epididymitis, hernia and hydrocele are the most common causes of acute scrotum. The clinical symptoms of AISE are usually mild and the characteristic Doppler sonography findings make it a valuable differential diagnosis, which can help to avoid unnecessary exploration.

Acute scrotum is a challenging emergency situation in children, adolescents and adults with a variety of underlying conditions and causes. In cases with a clinical suspicion of torsion of the spermatic cord, immediate surgical exploration is mandatory. This article details the surgical management of this condition. Any delay in restoring testicular blood supply may cause irreversible loss of vital testicular tissue.
